So we all live together, me, DP, dc, mum and my sis. Not an issue, we all like to watch certain things as a family, DS 16 literally only watches 3 Tv shows, big brother, I’m a celeb and ant and dec Saturday night takeaway. He’s recently been diagnosed with kerrataconus which is a thinning of the cornea. It causes blurry vision, and light sensitivity which means DS can’t watch Tv with the lights full blast as it cause glare and he can’t see much, we are waiting for an appointment for a slight operation and contacts to help with this, but nhs and especially our local hospital have a huge waiting list. My sister for some reason needs the light on 24/7, understandably when she’s eating, but after that she moan the lights need to be on, for no other reason, they generally get on but sometimes this causes a rift, we’ve all agreed to turn the light down but I’ve noticed DS still squinting. Obviously it’s a family home so everyone is entitled to have a say but she can’t give me a clear cut reason why the light needs to be on. My mums had several arguments with her about it too, the light is off 1hr/ 1 1/2 hours max but she’s still kicking up a fuss. I’m not sure how to rectify this as no one’s in the wrong, I’d just appreciate a little less attitude for something DS can’t really help. He barely comes out of his room usually.
